Abstract
The present invention is a self-priming pump incorporating an impeller coupled to the shaft of a drive motor between a rear casing coupled to the drive motor and a front casing which has an intake hole and a discharge hole and is formed with a U-shaped travel recess; wherein the impeller has an inner ring and an outer ring and a plurality of rotary blades extending radially between the inner ring and outer ring centred on the inner ring, the surface on one side in the direction of rotation of the rotary blades is formed with an inclined surface which is inclined at a predetermined angle from front to rear, and the rear-end part is formed with a pressure plate which partially obstructs the open space created between neighbouring rotary blades. The present invention has the advantageous effect that, despite a straightforward structure, it is possible to generate a large force of pressure on a fluid and so increase the discharge pressure and discharge volume and also reduce the frictional resistance resulting from the fluid flow, thereby increasing pumping efficiency.
